Research in Autodesk Inventor weldment performance cultivator frame

Abstract The paper examines issues of calculation in the welded frame structures design of engineering objects using as the example optimizing the cultivator frame. Design environment – Autodesk Inventor Professional. The purpose of the study was to reduce the cost of the base product. The basis for solving this problem is the development solid-state model of the cultivator frame basic construction; strength calculation of the frame with various options for its loading; the choice of the application of forces to the frame, leading to the occurrence of maximum stresses in the frame elements; the use of this option to analyze the strength of the frame after making changes to its design. In this paper, we investigated the possibility of replacing the steel grade of which the frame beams are made with St3ps steel; the possibility of making frame beams from a steel roll-formed channel is investigated. The possibility of reducing more than 30 percent of the frame mass by means of implementing the indicated actions is substantiated.
